According to the invention, at least two of the blind holes ( 7, 8, 9, 10 ), preferably all of the blind holes ( 7, 8, 9, 10 ), are fluidically connected together at a distance from the respective upper blind hole edges ( 11, 12, 13, 14 ).

BACKGROUND OF THE INVENTION

The invention relates to a device (rapid vapor generator) for generatingdecontamination agent vapor, in particular hydrogen peroxide vapor,comprising a single- or multipart evaporator body, a heating device forheating the evaporator body as well as at least one supply channel,preferably multiple supply channels for supplying a liquiddecontaminating agent to be evaporated, in particular hydrogen peroxide,to at least one of multiple blind holes arranged in the evaporator body,and to a flow channel arranged above upper blind hole edges and whichconnects an inlet for a gaseous carrier medium, in particular air, to anoutlet in a gas-conducting manner, for discharging the decontaminatingagent vapor through the outlet in a flow direction of the carriermedium.

The invention further relates to a preferably pharmaceuticalarrangement, comprising a space to be decontaminated, in particular anisolator and/or a port and a device for generating decontaminating agentvapor.

Furthermore, the invention relates to a method for operating a devicefor generating decontaminating agent vapor.

For decontaminating insulators and/or locks, hydrogen peroxide vapor,due to the high reactivity thereof, is used in the pharmaceuticalindustry. This vapor is obtained by evaporating an aqueous hydrogenperoxide solution. For minimizing the risk of explosions whenevaporating hydrogen peroxide-containing solutions, so-called rapidevaporators (rapid vapor generators) are used with the objective tocontinuously abruptly (rapid) evaporate small amounts of hydrogenperoxide-containing liquid. Boiling greater amounts of hydrogenperoxide-containing liquid is not permitted due to the above-mentionedexplosion risk. The difficulty in evaporating small amounts of hydrogenperoxide-containing liquid, in particular aqueous solutions, is theformation of liquid drops “dancing” on a hot evaporator surface whichinterfere with the efforts of a rapid evaporation.

A hydrogen peroxide vapor generator is known from DE 10 2006 006 095 A1and comprises a planar evaporator surface. Here, the above-mentioned“dancing” formation of droplets may occur.

An alternative rapid evaporator (flash evaporator) is known from EP 0927 159 Bland characterized by evaporator channels arranged in hydrauliccommunication in an evaporator body. The structure is relativelycomplex.

Reference is made to DE 602 03 603 T2 or DE 603 00 820 T2 regardingfurther prior art.

DE 2005 030 822 Aldiscloses a hydrogen peroxide evaporator with apot-like housing and an evaporator body which comprises one single,extensive evaporator surface, wherein the heat supply in thedecontamination agent is effected exclusively from below. The knownevaporator seems to be in need of improvement regarding its evaporatingrate and regarding the prevention of “dancing” decontamination agentdroplets. In addition, DE 2005 030 822 A1 discloses to connect multipleevaporators with a vessel to be sterilized via a respective line toincrease the amount of decontamination vapor. The overall evaporatorcosts thus result many times. Additionally, a plurality of vapor linesmust be guided into the space to be vaporated, which is problematic insmall spaces due to a lack of space. Additionally, a plurality ofsealings has to be provided.

CN 2009 43844 Y discloses an evaporator for water. The known evaporatorcomprises an evaporator body with a plurality of small openings. Asingle intake channel is commonly assigned to these holes, the channelbeing arranged centrally above the evaporator body. In order that theplurality of small openings can contribute to the evaporation, asufficiently great amount of liquid must be supplied through the onlysupply channel which in turn would run counter a spontaneous rapidevaporation of decontamination agents. In practice, a dangerousvaporization of decontamination agent would occur. Therefore, the knownevaporator is not suitable for evaporating decontamination agent.

EP 1 738 777A1 discloses an evaporator for a sterilization apparatushaving four supply channels, through which liquid decontamination agentis sprayed on a heatable plate. The evaporator surface can comprisedepressions, for example in the shape of hemispheres.

All rapid evaporators mentioned above are characterized by a comparablycomplex structure and/or an evaporation rate in need of improvement.

In EP 2 448 602 B1, a rapid evaporator significantly improved comparedto the above-mentioned prior art, which stands out due to the fact thatin the single- or multipart evaporator body of the rapid evaporatormultiple blind holes are provided, to which in each case at least one ofthe supply channels is assigned and wherein the supply channels areconfigured in such a way that the decontaminating agent to be evaporatedcan be supplied dropwise directly to the blind holes. This improvedrapid evaporator stands out due to a high evaporating rate and “dancing”liquid decontaminating agent drops are widely prevented within theevaporator as the evaporation takes place within circumferentiallyclosed blind holes in the evaporator body. The improved rapid evaporatorhas proved of value—however, there are efforts to increase the selectionsafety, in particular in the case where one of the supply channels mightfail.

SUMMARY OF THE INVENTION

In view of the above-mentioned prior art, the object underlying theinvention is to provide a rapid evaporator for decontamination agentswhich is characterized by high operational safety and, at the same time,a high vaporization rate with at least widely preventing “dancing”decontaminating agent drops.

Further, the object is to provide a (decontamination) arrangement with aspace to be decontaminated and a correspondingly improved rapidevaporator as well as an optimized operating method for a rapidevaporator according to the invention.

This object is achieved, regarding the rapid evaporator with thefeatures disclosed herein, i.e. in a generic rapid evaporator in that atleast two of the blind holes, preferably all blind holes, are connectedto one another in a fluidic manner at a distance to their respectiveupper blind hole edges.

Regarding the arrangement, the object is achieved with the featuresdisclosed herein and regarding the operating method also with thefeatures disclosed herein, i.e. in a generic method in that liquiddecontamination agent supplied in one of the blind holes flows into oneof the blind holes and there is evaporated into decontamination agentvapor.

Advantageous developments of the invention are provided in the dependentclaims. All combinations of at least two features disclosed in thedescription, the claims and/or the figures fall within the scope of theinvention.

To avoid repetitions, features disclosed according to the device areconsidered to be disclosed according to the method and be claimable.Similarly, features disclosed according to the method are considered tobe disclosed according to the device and be claimable.

The idea underlying the invention is to connect at least two blind holesarranged in the evaporator body at a distance to the blind hole uppersurfaces, i.e. below a circumferentially closed section of each blindhole in a fluidic manner, preferably by interconnected, so that theliquid decontamination agent supplied in one of the blind holes can flowin at least one neighboring blind hole at a distance to the flow channelformed above the blind holes. In other words, at a distance to the flowchannel in which the decontamination agent vapor originating in theblind holes and ascending upward with the help of a carrier medium, inparticular air, is transferred into the space to be decontaminated, atleast one connecting channel is to be arranged between two blind holesin the evaporator body which enables a distribution of liquiddecontamination agent between at least two blind holes. Thereby, theevaporator capacity of a blind hole in which the liquid decontaminationagent is interrupted, for example due to a blocked supply channel, canfurther be used to evaporate liquid decontamination agent flowing out ofat least one other blind hole and thus ensure a continuous supply of thespace to be decontaminated with a high decontamination agent vaporvolume flow. In this way, the rapid evaporator according to theinvention (flash evaporator) ensures a high evaporating rate due to theprovision of the blind holes in the evaporation body and furthermore ischaracterized by an increased fail-safety, as even in case of one ormultiple supply lines failing, a great evaporator surface is atdisposal. In a rapid evaporator designed according to the concept of theinvention, a great amount of heat can be supplied to the liquiddecontamination agent to be evaporated, preferably supplied dropwise,namely not only from above but also through radiant heat from thecircumferential walls of the blind holes. Preferably, the liquiddecontamination agent to be evaporated is an aqueous solution ofhydrogen peroxide, particularly preferably a 35% to 50% solution.

An embodiment is particularly preferred in which in each case at leastone of the supply channels is assigned to the blind holes and the supplychannels are arranged in such a way that the liquid decontaminationagent to be evaporated can be supplied directly in each of the blindholes, in particular dropwise. The configuration according to theinvention of the rapid evaporator, however, also for an alternativedesign variant, simpler in structure and more cost-effective, in whichindividual supply channels are intentionally omitted, i.e. in which notall blind holes have a supply channel assigned thereto but at least oneof the blind holes connected to one another in a fluidic manner and thedistribution of the liquid decontamination agent is not or notexclusively effected via the supply channels but at least partly via theliquid-conductive connections below the flow channel. In such anembodiment, “dancing” drops are prevented due to the distribution of theliquid decontamination agent and the high evaporating capacity of theblind holes is made use of.

It is particularly expedient, irrespective of the selection of one ofthe above-described modification variants, if the present supplychannels, are guided through the flow channel, preferably perpendicularto the longitudinal extent of the flow channel, for example in the formof injection needles, and end below the respective upper blind hole edgewithin the respective blind hole, preferably in such a way that theliquid decontamination agent exiting from the supply channels can dropdirectly down on the blind hole bottom in case of a vertical free fall.By penetrating or permeating the flow channel with the at least onesupply channel, carrying along of the liquid decontamination agent dropwith the carrier medium in the direction of the outlet can definitely bereliably prevented.

In view of the specific configuration of the blind holes, there aredifferent options. It is preferred if the blind holes extend larger indepth than to the sides. In other words, the maximum diameter of theblind holes in a circumferentially closed region, i.e. above a fluidicconnection, is greater than the respective extension in depth. Acylindric contouring of the circumferentially closed region above thefluidic connection has proven particularly advantageous.

As already mentioned, the blind holes are characterized by a sectionhaving a circumferentially closed shell surface, and adjoins the upperblind hole edge. Below this circumferentially closed shell surface, thefluidic connection according to the invention is then provided.

Preferably, the blind holes are arranged in a solid block (evaporatorblock) and further preferably produced as bores, whereby an extremelysimple and effective structure of the evaporator device is ensured.

It is particularly expediently, to configure and/or control the heatingdevice in such a way that the device heats the evaporator body to atemperature of a temperature range of between 100° C. and about 140° C.at least in the region of the blind holes. More particularly preferably,the temperature during evaporating operation is about 120° C. or less,to optimally prevent the drops not immediately evaporating on theevaporator surface, i.e. on the blind hole bottom.

Particularly preferably is an embodiment of the rapid evaporator inwhich the fluidic connection between at least two blind holes isconfigurated in such a way that the connection connects the lowestregions, i.e. the blind hole bottoms with a straight (planar, preferablyhorizontal) connection plane—in other words, the lowest regions of theblind holes connected to one another in a fluidic manner and the base orthe bottom of the connection, in particular of a connection channel, arelocated in a common plane to ensure an even distribution of the liquiddecontamination agent and to prevent an accumulation in the fluidicconnection or in the connection channel. By the fluidic connectionconfigured as described above, it is also ensured that the liquid doesnot have to overcome a step upward to get into the region of the fluidicconnection or the connection channel.

As already indicated, the liquid-conductive connection between at leasttwo blind holes is preferably configured as a circumferentially closedchannel, arranged at distance to the flow channel, in the evaporatorbody. It is particularly preferably, if at least one of the blind holesis connected to another or neighboring blind hole in a fluidic mannervia in each case such a connection channel. Here, the connection channelbridges over the distance between two neighboring blind holes in thetype of a tunnel below the flow channel.

Instead of realizing individual connection channels between neighboringblind holes, it is alternatively also conceivable to establish a commonconnection space which is preferably not interrupted by perpendicular orvertical pillars arranged therein—thereby, the directly heated base andthus the effective evaporator surface can be increased.

Irrespective of the specific configuration of the at least one fluidicconnection as connection channel or as a common space not interruptedfor example by an upward-running pillar, in particular not in thesurface extension, the fluidic connection is characterized by the factthat it is limited upward by a ceiling region which is arranged belowthe flow channel—in other words, in a liquid-conductive connection,there is no direct perpendicular connection path to the flowchannel—rather, the decontamination agent vapor has to ascend firstlaterally and then in the blind holes upward into the flow channel.

It has proven particularly expediently if a floor area or base surfaceof the fluidic connection, in particular of a connection channel, isconfigured as an evaporator surface heatable by the heating device sothat decontamination agent vapor can already be generated thereon,wherein the decontamination agent vapor can ascend upward via the blindholes in each case neighboring the connection channel or connected viathe flow channel. By means of this measure, the evaporation performanceis further increased while maintaining a constant construction size. Theevaporation performance within the fluidic region is particularly highdue to this region being limited by the ceiling area.

It has proven particularly expedient if the fluidic connection, inparticular an above-mentioned connection channel or the commonconnection space is produced from the solid, i.e. by material removalwithin a material block, in particular a high-grade steel block, inparticular by milling in radial direction with respect to thelongitudinal center axis of the blind holes. This can, for example, berealized in that a milling device is introduced into a blind hole andthen is adjusted laterally, i.e. in radial direction toward theneighboring blind hole.

Leak tightness problems, as they could occur if the evaporator body isconfigured tray-like or in a two-piece structure in the region of thefluidic connection, can definitely be prevented by the configuration ofthe fluidic connection in a full material body. Thus, it is essentialthat the evaporator body, at least in the region of the fluidicconnection is not configured multipart or does not have a joint or ajunction but is configured as a full material block.

As explained, the upper edge of the blind holes is spaced perpendicularto the flow direction of the carrier medium in the flow channel betweeninlet and outlet by a full material region in which the blind holes areconfigured circumferentially closed. In view of the geometricconfiguration of the flow channel, there are different options.According to a first alternative, the flow channel comprises a planarbottom so that the blind hole edges of the blind holes connected to oneanother fluidically at a distance to the bottom, preferably of all blindholes, are arranged in a common plane. Alternatively and preferably, anembodiment can be realized in which the upper blind holes are notarranged in a common plane but in a bent bottom region of the flowchannel. This embodiment allows for a bent, in particular cylindricalconfiguration of the flow channel which leads to more optimized flowconditions in the channel.

Also in view of the relative arrangement of two blind holes connected toone another fluidically, there are different alternatively, inparticular however additionally realizable options. At least two blindholes connected to one another fluidically can be spaced from oneanother in direction of the flow direction of the carrier medium in theflow channel and/or perpendicular to this flow direction. Particularlypreferably is at least a quad arrangement of blind holes in which thelongitudinal center axes of the blind holes limit the corners of avirtual rectangle, preferably a square. In a quad arrangement,preferably each of the blind holes has a neighboring blind hole alongthe longitudinal extent of the flow channel as well as a neighboringblind hole perpendicular thereto. It is even further preferably if eachof the blind holes is connected to the blind hole in the longitudinalextent of the flow channel as well as to the neighboring blind holeperpendicular thereto.

To further optimize the evaporation performance, it has provenadvantageous to arrange the heating device not laterally offset to thelongitudinal center axis or the center of a blind hole bottom, but insuch a way that the virtual extensions of the respective blind holelongitudinal center axis intersect the heating device. Preferably, theheating device comprises at least one channel arranged in the evaporatorbody in which channel a resistance heating according to correspondingabove definitions is arranged.

The invention also relates to a decontamination arrangement, comprisinga space to be decontaminated, in particular an insulator and/or a lockand a device (rapid evaporator) configured according to the concept ofthe invention for generating decontamination agent vapor. The space isconnected to the outlet of the flow channel of the rapid evaporator in avapor-conductive manner. Preferably, air, in particular ambient air, issuctioned as carrier medium and introduced in the flow channel via thecarrier medium inlet.

The invention also relates to a method for operating a device configuredaccording to the concept of the invention for generating decontaminationagent vapor, wherein liquid decontamination agent, in particularhydrogen peroxide, is supplied, preferably supplied dropwise, via the atleast one supply channel in at least one of the blind holes. Accordingto the invention it is provided that at least part of a liquiddecontamination agent supplied to one of the blind holes flows in atleast one other of the blind hole (connected to this blind hole in afluidic manner) and there is evaporated to decontamination agent vapor.A higher operational safety results from this method as a greater, inparticular the total evaporator surface is still at disposal even incase of failure of one supply channel.

In a further development of the invention, it is advantageously providedthat also part of the liquid decontamination agent flowing in directionof a neighboring blind hole via the liquid-conductive connection isalready evaporated in the fluidic connection, preferably in such a waythat the emerging decontamination agent vapor, distributed to thedirectly connected blind holes, can flow upward in the flow channel.Additionally or as an alternative, it is provided that the liquiddecontamination agent can flow in at least one further blind hole, whichis in turn fluidically connected to the neighboring blind hole via adirectly connected or fluidically connected blind hole.

It is more particularly preferably if the volume flow, i.e. the amountof the liquid decontamination agent supplied to the total number ofblind holes per unit time, is held constant, in particular irrespectiveof the number of supply channels currently on disposal. This can berealized in that the speed of flow in the other supply channelsautomatically increases with constant volume flow, if one of the supplychannels fails. In that the blind holes are fluidically-connected to oneanother at a distance to the flow channel, the liquid decontaminationagent can optimally distribute and thereby a great evaporator surface isat disposal so that the operation of the rapid evaporator is notnegatively influenced and the decontamination time does not need to beincreased. Holding the volume flow constant, can be realized by a volumeflow control wherefore a corresponding flow meter is arranged in asupply line for decontamination agent and a pump is controlled in such away via control means connected to the flow meter in a signal-conductivemanner that the volume flow is at least approximately held constant.

Further advantages, features and details result from the followingdescription of preferred exemplary embodiments and by means of thedrawings.

DETAILED DESCRIPTION

FIG. 1 to FIG. 4 show an evaporator body 1 of full material, herehigh-grade steel. The evaporator body 1 forms the core constituent of arapid evaporator otherwise not shown in detail and described for examplein EP 2 488 602 B1 as well as a (decontamination) arrangement shownthere in FIGS. 10 and 11.

A flow channel 2 is formed in the evaporator body 1 which connects acarrier medium inlet 3 to an outlet 4 in a gas-conducting manner. Aflange 5, 6 is in each case assigned to the carrier medium inlet 3 andthe outlet 4 with which the evaporator body 1 can be connected orflanged to corresponding lines or in the case of the outlet 4 directlyto a space to be decontaminated, if need be. A carrier medium, inparticular air is supplied via the carrier medium inlet 3 which mediumthen carries along the decontamination agent vapor emerging in theevaporator body 1 into the space to be decontaminated.

For the decontamination agent vapor generation per se, multiple, in thepresent example a total of four blind holes 7, 8, 9, 10 are provided,which are produced by drilling. An upper blind hole edge 11, 12, 13, 14is located in a bent region of the cylindrically contoured flow channelbelow an upper opening 15 which is closed in a completely mounted rapidevaporator and which is penetrated by supply channels (not shown), inparticular formed by injection grout needles, which permeate the flowchannel 2 perpendicular to the longitudinal extent thereof and in eachcase end in one of the blind holes 7, 8, 9, 10. As described in thegeneral description, it is not mandatory necessary, though preferred, toassign a distinct supply channel to each of the blind holes 7, 8, 9, 10as the liquid decontamination agent, as will be described later,can/will be distributed at distance to the flow channel 2.

Below the blind holes 7, 8, 9, 10, reception bores 16, 17 running inparallel to the flow channel 2 are located which run directly below theblind holes 7, 8, 9, 10 and are intersected by virtual longitudinalcenter axes of the blind holes 7, 8, 9, 10. The heating device isreceived in the reception bores 16, 17 in the completely assembled rapidevaporator.

In each case a circumferentially closed blind hole section 18 adjoinsthe upper blind hole edge 11, 12, 13, 14 which section spaces respectiveneighboring of the blind holes. This blind hole section 18 comprising acircumferentially closed shell surface also spaces the flow channel 2 tofluidic connections 19 assigned thereto and which connect blind holes 7,8, 9, 10 below the flow channel 2.

FIG. 1 shows two fluidic connections 19, 20 and FIG. 2 additionallyshows the other fluidic connections 21, 22. In particular from FIG. 2can be seen that the blind holes 7, 8, 9, 10, more specific thenon-illustrated longitudinal center axes thereof, are arranged in arectangular form or limit the corners of a virtual rectangular, here anvirtual square, wherein each of the blind holes 7, 8, 9, 10 is connectedto two further of the blind holes via in each case a fluidic connection.

It can be seen, that the fluidic connections 19, 20, 21, 22 (cf. inparticular the synopsis of FIG. 1 and FIG. 2) are configured in eachcase as a circumferentially closed connection channel 1, i.e. as a typeof connection tunnel. The fluidic connections 19, 20, 21, 22 orconnection channels 1 have a (lowest) base 23, 24, 25, 26 which connectsthe lowest regions 27, 28, 29, 30 of the blind holes 7, 8, 9, 10, i.e.the blind hole bottoms to one another in a common plane.

It can be seen in FIG. 4 how the fluidic connections 19, 20, 21, 22 orconnection channels 1 are produced, namely by radial, i.e. lateralmilling, starting from an original blind hole bore. The correspondingmilling contours 32 can be seen in FIG. 4 and FIG. 2.

It can be taken in particular from FIGS. 2 and 4 that the blind holesarranged in a rectangle are separated from one another in a lowerregion, i.e. at one level with the fluidic connections 19, 20, 21, 22via a center pillar 33 which establishes the connection between theevaporator body region laterally of the circumferentially closed blindhole sections 18 and the evaporator body region below the lowest regions27, 28, 29, 30 of the blind holes 7, 8, 9, 10. In an alternativeembodiment, a center pillar 33 can be omitted by removing the materialforming the pillar, in particular by lateral milling, possibly whenarranging the blind holes closer to one another. Then, a commoninterrupted space is established as the liquid-conductive connectionbetween all of the blind holes. A such, the fluidic connection is alsocharacterized by a ceiling region radially neighboring the blind holes.

The liquid decontamination agent introduced, in particular dropwise, inone of the blind holes 7, 8, 9, 10 via a supply channel, can distributevia the fluidic connections 19, 20, 21, 22 so that using the entireevaporator surface is possible even if intentionally ornon-intentionally one of the blind holes 7, 8, 9, 10 is not directlysupplied from above with liquid decontamination agent via a supplychannel.

The configuration of the fluidic connections 19, 20, 21, 22 as in eachcase a circumferentially-closed connection channel means that thesecomprise a closed ceiling area with respect to the lower base 23, 24,25, 26 as well as side wall areas spaced apart from one another andconnecting the ceiling area to the base.
